Samsung has published the official Android 7.0 Nougat February 2018 firmware updates for all the 2017 Galaxy A7 smartphones.
Check the info in this post and learn how to install the update manually before the new firmware reaches your whereabouts over-the-air.
The new update is being released in stages and it packs the latest 2018 security patch and some new features that will improve your overall Nougat OS experience. Make sure that your Galaxy A7 (2017) meets all requirements below before starting the installation, as you'll need to apply some changes to your device first.
This guide has to be used only for the Samsung Galaxy A7 2017 devices. Don't try to flash this update for any other different Galaxy A7 models.
Download and install the Samsung USB drivers from here. The drivers will allow you to easily connect your phone with the PC via usb cable.
For Odin to work with your PC you also have to enable USB Debugging from Developer Options. If you can't find Developer Options, then you should first enable this menu:
- go to Settings> About Device> Software Info and tap seven times on the Build Number text.
- get back to Settings, open the Developer Options and enable USB Debugging.
This update can be flashed over rooted firmware, too, but you should know that root access won't survive the update.
Any custom Recovery that you might have flashed will be replaced with stock Recovery.
This new update can be installed over custom ROMs, but you need to know that an extra step has to be applied like Factory Reset. Without factory resetting the device your phone will not reboot in normal mode with the stock ROM, as it conflicts with the previous custom ROM installation.
- the factory reset steps are listed at the end of the tutorial.
- by factory resetting process will wipe clean the system partition, and it forces it to boot in normal mode.
If your Galaxy A7 2017 device runs 100% stock Android firmware, then you can start the update right away, as no data will be affected in the process.
Read the whole post and do not skip any steps.
Use the tutorial only if you are an advanced user, as we cannot be blamed in case you brick the phone nor in case you lose any important files.

- Now you need to load all the update files in ODIN:
Click the BL button and load the tar.md5 A720FXXU2BQL7 Android 7.0 file that has the "BL" in its title.
Click CP and load the tar.md5 file with "CP" in the name.
Click CSC and load the tar.md5 file with "HOME_CSC" in its name. Don't load the file with only "CSC" in the name, as that file will tell ODIN to wipe clean the phone, and you will lose all data.

If ODIN displays the FAIL alert, then you have to repeat the tutorial more than once. But, make sure to verify the "preparation steps" and see if the Galaxy A7 2017 meets all requirements listed there.
If the PASS alert is shown by the ODIN app, but your phone enters in a boot loop or it gets stuck at the boot animation screen, then you will have to Factory Reset the device.
The Factory Reset process has to be applied by those that have installed the Android 7.0 official update over a custom ROM, as otherwise the Galaxy A7 devices will not boot in normal mode. Here's how to apply the Factory Reset from Recovery Mode:
- power off the Galaxy A7 2017 device.
- boot the device in Recovery Mode.
- press and hold Volume Up + Home + Power buttons at the same time.
- release the buttons when the Recovery menu loads.
- select 'wipe data/ factory reset', and confirm process.
- reboot the device.
These were all the steps you had to go over before starting the installation process.
